Thanks for the reply guys. The data I've been reading is confusing to say the least. IMR data states no start load & a max of 22.0gns. compressed charge. But then some of the other data says up to 23.5 but it doesn't mention a compressed charge.
I think I'm going to go with the 22.0gn. load. The IMR data lists it at 1275fps/32,600cup. from a 8.5" barrel. That should be fine. I've never loaded a compressed charge before, does it up the pressure or whats the deal?
P.S. Since this is a slow burning powder it's my thinking that it should perform better out of a longer barrel. If so then I'll keep these rds. for my 7.5" Redhawk.
